I10: Issue10 tests; Test just to check if very long sequences are passing (jdk1.6 v jdk 1.7)

(improved pull request - sorry for sloppy first attempt)
test replicates the issue #10 
it does not "fix" it - but this is an issue with the java version when using
com.sun.org.apache.xerces.internal.impl.xpath.regex.RegularExpression.matchString(RegularExpression.java:1586)

see Issue comment for specifics #10
